We just purchased our i7 lastnight (first iMac) and was would like to know what brand of Ram would be best suited for our system? Been reading here that people recommend OWC,Crucial and G.Skill. Does any of them have a certain advantage over the other? We are looking at getting a total of either 12GB or 16GB. Here is the specs. to the system we ordered: 3.4GHz Quad-Core Intel Core i7 4GB 1333MHz DDR3 SDRAM - 2x2GB 2TB Serial ATA Drive AMD Radeon HD 6970M 2GB GDDR5 MAGIC MOUSE+MAGIC TRACKPAD IWORK Apple WL Kybd (English)+User's COUNTRY KIT,IMAC We are going to use the computer for mostly pictures as well as video editing with, more than likely, gaming in the future. Also, we are getting an external hard drive as back up and would like recommendations on a good 2TB one. Any good software should we consider? Hopefully this purchase is going to be our last desktop computer for a while so we configured it more than we needed. Any help would be more than greatly appreciated! P.S. We are making the transition from PC to Apple so be nice.
